[lld][WebAssembly] Convert some lld tests to assembly When we originally wrote these tests we didn't have a stable and fleshed out assembly format. Now we do so we should prefer that over llvm ir for lld tests to avoid including more part of llvm than necessary in order to run the test. This change converts just 30 out of about 130 test files. More to come when I have some more time. Differential Revision: https://reviews.llvm.org/D80361

[WebAssembly] Add --[no]-export-dynamic to replace --export-default In a very recent change I introduced a --no-export-default flag but after conferring with others it seems that this feature already exists in gnu GNU ld and lld in the form the --export-dynamic flag which is off by default. This change replaces export-default with export-dynamic and also changes the default to match the traditional linker behaviour. Now, by default, only the entry point is exported. If other symbols are required by the embedder then --export-dynamic or --export can be used to export all visibility hidden symbols or individual symbols respectively. This change touches a lot of tests that were relying on symbols being exported by default. I imagine it will also effect many users but do think the change is worth it match of the traditional behaviour and flag names. Differential Revision: https://reviews.llvm.org/D52587 llvm-svn: 343265

[WebAssembly] Rename WasmLimits::Initial to ::Minimum. NFC. This patch renames the "Initial" member of WasmLimits to the name used in the spec, "Minimum". In the core WebAssembly specification, the Limits data type has one required "min" member and one optional "max" member, indicating the minimum required size of the corresponding table or memory, and the maximum size, if any. Although the WebAssembly spec does instantiate locally-defined tables and memories with the initial size being equal to the minimum size, it can't impose such a requirement for imports. It doesn't make sense to require an initial size for a memory import, for example. The compiler can only sensibly express the minimum and maximum sizes. See https://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md#naming-of-size-limits for a related discussion that agrees that the right name of "initial" is "minimum" when querying the type of a table or memory from JavaScript.

[WebAssembly] Add missing function exports and SYM_INFO to --relocatable output When writing relocatable files we were exporting for all globals (including file-local syms), but not for functions. Oops. To be consistent with non-relocatable output, all symbols (file-local and global) should be exported. Any symbol targetted by further relocations needs to be exported. The lack of local function exports was just an omission, I think. Second bug: Local symbol names can collide, causing an illegal Wasm file to be generated! Oops again. This only previously affected producing relocatable output from two files, where each had a global with the same name. We need to "budge" the symbol names for locals that are exported on relocatable output. Third bug: LLD's relocatable output wasn't writing out any symbol flags! Thus the local globals weren't being marked as local, and the hidden flag was also stripped... Added tests to exercise colliding local names with/without relocatable flag Patch by Nicholas Wilson!

[WebAssembly] Don't error when --undefined symbols are not found This matches the behavior of the ELF linker where -u/--undefined means symbols will get pulled in from archives but won't result in link error if they are missing. Also, don't actually great symbol table entries for the undefined symbols, again matching more closely the ELF linker. This also results in simplification of the code.

[WebAssembly] Add test of indirect call to an otherwise unused type In this case we are calling a function pointer which a type that doesn't otherwise exist in the code. Clearly this code can't would trap if it was ever called (because there is not such function that the pointer can resolve to). But it should valid and compile and link and validation time. llvm-svn: 321134

Revert "[WebAssembly] call_indirect issues table number relocs" This reverts commit 418df4a6ab35d343cc0f2608c90a73dd9b8d0ab1. This change broke emscripten tests, I believe because it started generating 5-byte a wide table index in the call_indirect instruction. Neither v8 nor wabt seem to be able to handle that. The spec currently says that this is single 0x0 byte and: "In future versions of WebAssembly, the zero byte occurring in the encoding of the call_indirectcall_indirect instruction may be used to index additional tables." So we need to revisit this change. For backwards compat I guess we need to guarantee that __indirect_function_table is always at address zero. We could also consider making this a single-byte relocation with and assert if have more than 127 tables (for now). Differential Revision: https://reviews.llvm.org/D95005
